Tesseract: in Cocoa Touch Framework cannot open eng.traindata file

I got following errors when I run iOS application, with embedded binary which is my own cocoa touch framework with following dependencies

1) TesseractOCR.framework
2) CoreImage.framework
3) libstdc++.6.0.9.tbd
4) libz.tbd

I got 1) TesseractOCR.framework by using instructions (Non-Cocoapods Installation) from this link https://github.com/gali8/Tesseract-OCR-iOS/issues/340#issuecomment-351479701

The reason I do not use TesseractOCR from Cocoapods is that I need to create custom OCR framework which will be used by clients.

I also have tessdata folder reference with trained data files inside my own cocoa touch framework.

When I tried to create and debug single view app with above listed dependencies and the tessdata, which is working fine.

But my iOS application with my framework will get following error message

Error opening data file file:///var/mobile/Containers/Data/Application/9669A787-B512-4C02-8DA7-8E77FBEF7B8A/Documents/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!

Here is my folder structure of my framework.

In order for My-Application (Client App) to work, I have to add tessdata as a reference to client app. Currently, there are no other ways without it.
